CUT IT HIGH.
SET MOWERS TO 4 INCHES
The Shade Shield
Taller blades act as thousands of umbrellas, shading the soil from direct sun and preventing high-intensity heat spikes.
Fewer Ant Mounds
Ants "push up" and build tall mounds to regulate their home's temperature. Shaded grass keeps the ground cool and keeps ants calm.
Less Water Waste
Scalped grass has shallow roots. Taller grass grows deep roots that hold moisture, reducing brown patches and water bills.
Elite Standard
Professional golf courses and elite landscapes maintain grass height for strength and aesthetics. Scalping is a sign of poor maintenance.

Using Science to Cool Our Community
The "Shade Shield"
Natural Cooling
When grass is 4" tall, the blades act like thousands of tiny umbrellas. They shade the soil from direct, high-intensity sunlight.
Magnified Heat
Without shade, short grass soil absorbs radiant heat . Even in 100° weather, unshaded soil can spike way above the air temperature!
Short Grass Problem
UNSHADED SOIL
"Short grass lets the sun bake the dirt directly, creating a localized heat spike that stressed roots can't handle."
Fire Ant Physics
The "Push Up"
Fire ants build large mounds to regulate their home's temperature. When the ground gets too hot, they push up to reach the surface and cool off.
The Calm Zone
Taller grass keeps the soil cool and stable. Ants don't need to build massive "cooling towers" (mounds) because the shade does the work for them.
Stronger Roots,
Lower Costs
The 1/3 Rule
Never cut more than 1/3 of the grass height at once. This prevents "shocking" the plant and keeps it green.
Water Efficiency
Deep roots (from taller grass) find water deeper in the soil. This saves money on irrigation bills!
STAY GREEN
A healthy lawn is a tall lawn.

Research & Resource Management: Campus Cooling
Science Dept
Inquiry-Based Learning
The Scientific Focus
This program focuses on Inquiry-Based Stewardship . Students observe the campus ecosystem and learn how resource management (lawn maintenance) affects soil health and local temperature. By sharing their findings as "Student Researchers," they contribute to a cooler, more sustainable campus environment through collaboration with facilities and families.
Key Concepts
Radiant Heat Absorption
Soil Temp Gradients
Behavioral Entomology
The Collaborative Approach
Teacher Note: Avoiding "Political" Friction
Frame this as a science project and resource optimization . Instead of "demanding change," students are "sharing campus research" with administrators and "optimizing lawn health" with families. This positions them as helpful stewards rather than political activists.
How to approach school staff:
"Our science class is researching 'Shade Shields' on campus. We found that keeping grass at 4 inches significantly reduces soil radiant heat. Would you be interested in seeing our data on how this could help our playground stay cooler?"
Entomology Data
"Fire ants build mounds to regulate their internal nest temperatures. By keeping the grass taller, we cool the ground naturally, reducing the ants' need to 'push up' into mounds where students play."
Root Architecture
"Science shows that root depth is proportional to blade height. Taller grass means deeper roots, which prevents erosion and reduces the need for frequent irrigation on campus."
Scientific Sharing Steps
1
Observation Phase
Have students measure grass height and map any heat-stressed patches or ant activity on school grounds.
2
Sharing Information
Distribute the Grass Roots Bilingual Cards . Frame these as 'Science Fact Sheets' to help families and grounds crews understand plant biology.
3
Campus Visuals
Position the Cool Campus Poster as an educational resource to inform the community about how we are using biology to cool the environment.
Science Extension
Have students use a 12-inch ruler to verify "The 1/3 Rule" (never cutting more than 1/3 of the blade). This reinforces math skills and plant physiology concepts simultaneously.

The Mission / La Misión
Investigate our campus "Shade Shield." We are looking for the relationship between grass height, soil appearance, and fire ant activity.
Location / Ubicación Grass Height / Altura Soil Appearance / Suelo Ant Mounds? / ¿Nidos? Example: 1 inch Dry / Cracked Yes (Large)
1. The "Shade Shield" Analysis / Análisis del Escudo
Where was the grass healthiest? How did the height of the grass affect the soil? / ¿Dónde estaba el pasto más sano? ¿Cómo afectó la altura del pasto al suelo?
2. The Fire Ant Connection / La Conexión de Hormigas
Did you find more mounds in short grass or tall grass? Based on our "Push Up" science, why do you think that is? / ¿Encontraste más nidos en pasto corto o alto? Según la ciencia de "empujar hacia arriba", ¿por qué crees que sea así?
3. Stewardship Recommendation / Recomendación
What setting should our campus mowers be set to? Why? / ¿A qué nivel deberían ajustarse las podadoras de nuestro plantel? ¿Por qué?
Scientific Data for a Greener Community

CORTA ALTO.
PODADORAS A 4 PULGADAS
Escudo de Sombra
El pasto alto actúa como miles de sombrillas, protegiendo el suelo del sol directo y evitando picos de calor intenso.
Menos Hormigueros
Las hormigas construyen nidos altos para regular su temperatura. El pasto sombreado mantiene el suelo fresco y a las hormigas tranquilas.
Menos Agua
El pasto muy corto tiene raíces superficiales. El pasto alto desarrolla raíces profundas que retienen la humedad y reducen costos.
Estándar de Élite
Los campos de golf y paisajes de élite mantienen el pasto alto por salud y estética. Un corte excesivo es señal de mal mantenimiento.
